MECHANISM FOR OPERATINGIHE TWIST-SLIDES 0F SPINNlNG-MULES.

SPECIFICATION forming part of Letters Patent No. 432,013, dated July 15, 1890.

Application filed January 2, 1 8 90- T0 at whom it may concern:

Beit known that I, JOHN BOND, acitizen of the United States, and a resident of \Vaterloo, in the county of Seneca and State of New York, have invented certain new and useful Improvements in Mechanism for Operating the Twist-Slides of Spinning-Mules,of which the following is a specification.

Myinvention relates to the means employed in spinning-mules for operating the twistslide. I aim to diminish the force with which the carriage meets the stationary gearing or reversing mechanism whatever the degree of speed of travel may be, to prevent the rebounding of the carriage from the rolls, and thus avoid the injury to the yarn which results from a sudden or forcible shock, to diminish the amount of rope heretofore employed in pulling in the carriage, and to reduce the wear of the machinery and render it capable of being driven with less power than heretofore. These objects I attain by means of the n ovel features of construction illustrated in the accompanying drawings, in which Figure 1 isarear elevation of so much of a head-stock of a mule as will suffice to show the connection of my improvements therewith. Fig. 2 is an end elevation of the parts shown in Fig. 1, and also indicating the manner in which the carriage operates the same. Fig. 3 is a front elevation of so much of the headstock as pertains to my improvements in connection with the parts directly affected thereby; and Fig. 4 is a representation, in detail, of the various parts embraced in my improvements, the same being shown detached or separately in such manner as will best illustrate them.

Like letters of reference indicate like parts.

I-Ieretofore the twist-slide has been acted upon, primarily, by means of a roller (represented by the dotted or broken lines at a, Fig. 2) applied to the carriage A in such a position as to strike and lift an arm or finger *3, projecting from the twist-slide D. This roller, as well as the scroll heretofore employed to assist the drawing-in scroll, I dispense with, as will hereinafter more fully appear, it being understood by those familiar with machines of this class that the movement of the said finger varies, shifts, or controls Serial No. 335,581. (No model.)

hence of the various other parts of the mule.

I will now proceed briefly to describe the meanswhich I employ to lift the said finger, which means constitute my improvements and embody my invention.

E is a bracket. or hanger fastened to the frame a of the machine and depending vertically therefrom.

F is a lever supported by the said bracket and capable of being tilt-ed vertically. One end of this lever passes underneath the finger B, as is clearly shown in Fig. 3, and G is a movable weight upon the other end of the said lever.

I1 is a depending slotted guide fastened to the frame and through which the said lever passes. I

I is a catch-bar arranged vertically and pivoted or jointed to the said guide at b in such a manner as to be capable of swinging toward and from the said lever. The catch of the bar I is at c, and performs the function of supporting the lever F temporarily in its raised position, as will be more fully explained. A small spring d is connected to the upper end of the bar I and to a fixed part c. This spring holds the said bar yieldingly against the lever F. I

J is a slotted horizontal arm bolted to the lower end of the bar I and having a flattened end or head f. This bar is capable of being adjusted so that its head may be set at a greater or less distance from the bar I.

K is a swinging cam arm or lever depending from the frame and hinged or jointed thereto by means of a bracket 9 and a bolt g? and nut or in any suitable or well-known way.

71 is an opening in thelever K, and the lever F passes freely through the said opening, which is elongated, as shown, in the direction of the swing of the lever K, which is toward and from the lever F.

L is a spur-wheel turning on a bearing L, rigidly applied to the frame and engaging a pinion M fixed on the shaft N, which constitutes a part of the means employed for reversing the movement of the carriage.

O is a stud or pin projecting laterally from the wheel L and arranged to bear upon the the action or operation of the twist-slide, and

' nor do I wish to be limite under sideor edge of the lever K, and raises the same as the wheel L is rotated.

The operation of the parts constituting my mprovements is as follows: As the carriage is drawn in, it meets the headfof the arm J, tilts the bar I away from the lever F until the catch projection 0 passes from under the said lever, the weighted end of which then drops down while the other end is tilted up, and raises the finger B, which, as before stated, projects from the twist-slide, so that the latter is therefore lifted, with the result, among other consequences, that the movement of the carriage is reversed. As the carriage is drawn out, the stud 0 passes under the lever K, tilts or raises it, which in turn raises the Weighted end of the lever F and depresses the other end, thus releasing the finger B, which gradually moves down as the lever F is lifted, and reaches a point at or ust above the catch projection 0, when the spring cl causes the said catch to pass underneath the lever F and supports it there until the carriage again strikes the end of the arm J, when the operation now described is repeated.

It is to be understood that the operation of the other parts or combination of parts in machines of this class is substantially the same as heretofore, and I have not therefore here particularly described the construction and operation of such parts, the same being old and well known. I desire to state, however, that by reason of myimprovements the force with which the carriage meets the head f is greatly reduced owing principally to the fact that the lever F is released from its raised position very easily and performs by reason of its gravity much of the work heretofore done'by the then necessarily heavy blow upon the finger B as the carriage moved in. There is therefore little or noshock and rebounding and very much less liability of consequent injury to the yarn. It will also be perceived that there is 1n consequence of my improvements no necessity for employing an auxiliary pulling-in scroll, that the wear of the machinery is reduced, and that it may be driven with less power than formerly. I also desire here to state that I do not here intend to restrict myself to mere form and detail of construction,

to any particular use to which my improvements may be applied with advantage. My improvements, however, are principally intended for operation-in connection with spinning-mules and spinning-jacks.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, with the carriage of a spinning mule or jack and the twist-slide of the operatinggear, of a gravitating lever bearing on the said slide and a yielding or tilting lever-support arranged to be struck by the carriage, substantially as and for the purposes specified.

3. The combination, in self-acting gear for operating spinning-machines, of the twistslide, a gravitating lever acting on said slide, a yielding catch for temporarily supporting the said lever, and a lever-lifter in connection with the drawing-in shaft, substantially as and for the purposes specified.

4. The combination, in self-acting gear for operating spinning-machines, of the carriage, a movable arm consisting of two members I and J, the twist-slide, and a gravitating lever supported in its raised position by means of said arm and acting on the twist-slide, substantially as and for the purposes specified.

5. The combination, in a self-acting spinning-machine, of the carriage A, the slide D, the gravitating lever F, the catch I J c, the cam or lever K, the gear L, carrying the stud O, and the pinion M, substantially as and for the purposes specified.

6. The combination, in self acting or operating spinning-machines, of the carriage, the twist-slide, the lever F, the guide H, a yielding and adjustable lever support or catch, the

cam or lever K, the gear L, with its stud O,

and the pinion M, substantially as specified,

and for the purposes set forth.
